Automated pre-processing strategies for species occurrence data used in biodiversity modelling [PDF]

open access: yes, 2010
To construct Biodiversity richness maps from Environmental Niche Models (ENMs) of thousands of species is time consuming. A separate species occurrence data pre-processing phase enables the experimenter to control test AUC score variance due to species ...

Influence of different data cleaning solutions of point‐occurrence records on downstream macroecological diversity models

open access: yesEcology and Evolution, 2022
Digital point‐occurrence records from the Global Biodiversity Information Facility (GBIF) and other data providers enable a wide range of research in macroecology and biogeography. However, data errors may hamper immediate use.

GBIF Data Processing and Validation [PDF]

open access: yesBiodiversity Information Science and Standards, 2021
GBIF (Global Biodiversity Information Facility) is the largest data aggregator of biological occurrences in the world. GBIF was officially established in 2001 and has since aggregated 1.8 billion occurrence records from almost 2000 publishers. GBIF relies heavily on Darwin Core (DwC) for organising the data it receives.

DNA barcoding and taxonomy: dark taxa and dark texts [PDF]

open access: yes, 2016
Both classical taxonomy and DNA barcoding are engaged in the task of digitizing the living world. Much of the taxonomic literature remains undigitized. The rise of open access publishing this century and the freeing of older literature from the shackles ...

Paying it forward: Crowdsourcing the harmonisation and linking of taxon names and biodiversity identifiers [PDF]

open access: yesBiodiversity Data Journal, 2023
Linking records for the same taxa between different databases is an essential step when working with biodiversity data. However, name-matching alone is error-prone, because of issues such as homonyms (unrelated taxa with the same name) and synonyms (same

Towards a biodiversity knowledge graph [PDF]

open access: yes, 2016
One way to think about "core" biodiversity data is as a network of connected entities, such as taxa, taxonomic names, publications, people, species, sequences, images, and collections that form the "biodiversity knowledge graph".
